Application filed June 24,

My invention refers to improvements in the class of tinning posts for; application of molten tin to the surfaces of black iron sheets. In such operation the sheet is usual- 1y introduced downwardly through a bath of molten tin and then upwardly, with a final passage through a superimposed body of 'oil, as palm oi rIn my present invention I provide oppol0 sitely arranged water circulating cooling walls at each side of the oil containing chamber with means for providing a copious water "circulation 'theret'hrough, and for cleaning out deposits of sediment from time to time. Also an improved construction of the-initialtinning compartment providing for con tinuous renewal supply of pig tin, together withother features ofconstruction and improvement, as hereinafter described. e, p

In the drawings, showing one preferred embodiment of the inven'tion, I

Fig. 1 is a plan view of the pot; Fig. 2 is a cross section on the line II, II,

ofFig.1;

Fig. 3 is alongitudinal vertical section on the line III, III, of Fig. 1;

Fig. 4: is a similar section on the line IV,

IV.ofFig.1;

Fig. 5 is a detail'section on the line V, V,

ofFig.2;

Fig.r6 is a similar horizontal section on the line vI,vI, of Fig. 2.

.The main body of the pot'consists of continuous U-shapedblank of plate-.metal bent'to provide a front wall 2, a bottom wall 3, a rearwardly inclined backwall 4, and, an upper rear vertical wall 5. V

The latter wall extends materially higher than front wall 2, providing for one side of the superimposed oil chamber B.

Theends of the pot are formed by closing end walls 6 of a suitable metalplate form, adapted to make a welded or .other'suitable and is welded to-the.bottom3,as at 11.

The ,flange 'Zbeing firmly, eldedito-the I edges. and sides of the end plate, as at 8, not only provides a contmuous homogeneous jomt, but likewise provides a" continuous tinning'compartment'into two chambers A and arespectively. 5

The lower front portions of. the end plates 6 are provided along their, upper edges with relnforcing flanges 13 ]OlI16 Cl with a similar front flange ldof the wall 2, and welded thereto as at15, the corners being preferably rounded as shown. Y j The lower front portions ofthe .end plates gee are provided, at one or both ends, with pock-v ets 16" formed by outwardly extending rectangular flat or inclined bottomed boxes 17,

Such bars are supplied by melting down under Ifrom'time to time, extending well below the p IOU securing outer enclosing walls 20 and 21 to the rear of wall 5 and to the front of partition 9 respectively, as in Fig. 2.

The rearcooling, chamber thus formed I preferably extends vertically, while the front chamber preferably inclines forwardly as 7 shown, in conformity with theinclined secbottoms.
